OCCURRENCE OF MULTICERCUS OF THE GENUS MIRCIA (CESTODA:
SCHISTOTAENIIDAE) IN DRAGONFLY LARVAE (ANIZOPTERA) IN
RUSSIA AND NEIGHBORING COUNTRIES
Regel K.V.
According to the literature and our own data, the occurrence of polycephalic metacestodes,
multicercus (or multicysticercoids) of the genus Mircia in larvae of dragonflies of Eurasia is presented.
The first find of such metacestodes in dragonfly larvae of Japan belongs to Yamaguti (1942), who
defined them as «cysticercus» of Tatria decacantha. Since, similar metacestodes were described
twice as T. decacantha from dragonflies of the Southern Urals. In the same place, Gulyaev describes
a new species (taxon) Joyeuxilepis uralensis Gulyaev, 1989 (syn. Т. decacantha larva sensu Tkatchev,
1969; Bayanov, 1974) for the polycephalic modification of metacestodes, which gives the name
“multicercus”. As a result of the revision of representatives of the genus Joyeuxilepis was created a
new genus and species Mircia shigini Konyaev, Gulyaev, 2006 (as type) and inscribe four more
species, including those listed above. Our research in the far north-east of Russia has shown, that
multicercus of M. shigini are widespread in the Okhotsk-Kolyma region and were found in dragonfly
larvae in 6 lakes on the northern coast of the Sea of Okhotsk and in 11 lakes of the Kolyma basin
(from its upper reaches to the polar regions — Chersky settlement). Finally, in May 2018, we managed
to find dragonfly larvae infected with multicerci on the Karelian Isthmus.
The result of comparative analysis of multicerci from the western border of the range (the
Karelian Isthmus) and from different sites of the Magadan region by the molecular genetic method
showed the identity of all compared samples! What will the samples from dragonflies of the South
Urals show?
